Thanks Sando7. To help clear up my confusion and ignorance, are all IMR batteries non protected?
you want 18650 IMR's 2000mAh "non protected", and this is a very reputable vendor and imo AW are the best.....would pick up at least 2 or even more.
don't skimp on a charger get a good one like one of these
